Why do cats chew on people's fingernails? - in detail
Cats chewing on people’s fingernails is a behavior that can stem from various instincts and habits. One primary reason is curiosity. Cats are naturally inquisitive creatures, and fingernails, with their texture and movement, can attract their attention. The hardness and smoothness of nails may mimic the feel of certain objects cats encounter in their environment, such as bones or small toys, prompting them to explore further. Another factor is teething, particularly in kittens. Young cats often chew on objects, including fingernails, to relieve discomfort as their adult teeth emerge. This behavior can persist into adulthood if not redirected. Additionally, cats may chew on fingernails as a form of grooming or bonding. In the wild, cats groom each other to strengthen social bonds, and this behavior can extend to their human companions. When a cat nibbles on a fingernail, it might be an attempt to engage in a similar social interaction. Stress or boredom can also drive this behavior. Cats may chew on fingernails as a way to self-soothe or to alleviate monotony, especially if they lack sufficient mental or physical stimulation. Lastly, the scent of lotions, creams, or residue on fingernails can attract cats, as their keen sense of smell might find these substances intriguing. Understanding the underlying cause of this behavior is essential for addressing it effectively, whether through providing appropriate chew toys, increasing enrichment, or consulting a veterinarian if it becomes excessive.
